(Cl. 19949) This invention relates to typographical slug Figure 1 is a horizontal sectional view of the casting machines such as those known commercifirst elevator head, the section, as to the left-hand ally under the trade mark Linotype, wherein part of the figure being taken in the plane indicirculating matrices are composed in line, the cated by the line AA of Figure 4, and as to the 5 line transferred to a vertically movable transright-hand part of the figure, in the plane indi- 5 porter or so-called first elevator, which is lowered cated by the line B--B of Figure 3, the devices to present the line to the mould for casting, and being represented in normal position;

The pawls 3 are depressed into 50 descr be With reference to the aeeempehying recesses 6 in the elevator head by the leading draw Which illustrate one constructional matrix of a line entering the elevator, and at (form of apparatus by which the invention may be their outer ends are provided with shoulders I carried out. adapted to be engaged by detents 8 which serve In the sa d. drewihgsi; l to hold the pawls in the Withdrawn position. The 55 pawls are also provided with shoulders 9 which engage the left-hand walls 6 of the recesses 6 when the pawls are withdrawn, thus cooperating with the detents 3 to retain the pawls in their withdrawn position at the receiving end of the elevator, as shown in Figure 2. The rails 5 to which the pawls 3 are secured are thus held against longitudinal movement during the delivery of the line to the elevator, while the resistant member 4 is moved for example from the position in which it is shown in Figure l to that in which it is shown in Figure 2. To permit this movement of the resistant member 4 relatively to the rails 5, the latter are frictionally secured to the said member. The desired connection is conveniently effected by means of studs l8 passing through slots l l in the respective arms of the resistant member 4 and bearing thereon through friction washers I2, the heads of the studs Hi and the washers l2 lying within longitudinal recesses I 3 formed in the inner faces of the resistant member 4.

When delivery of the line to the first elevator is completed, the known delivery slide right-hand finger l4 releases the detents 8, thus permitting the pawls 3 to return to their active position in which they engage behind the terminal matrix of the line.

As shown in Figure 3, the detents 8 are carried on horizontal pivots it: in the elevator head and are held in active position by springs I5 acting upon the detents above the pivot. At their upper ends the detents 8 are provided with lateral extensions I! which lie in the path of the delivery finger M to enable the latter as it enters the first elevator at the end of the line delivery stroke to eirect the release of the detents as above mentioned.

It will now be understood that when a line of matrices is to be quadded or centred and the line is for this purpose moved towards the left as viewed in Figures 1 and 2, the line resistant member 4 will be taken with it and also the rails 5 and pawls 3, since the latter are free to move longitudinally, and will be so moved through the stud and washer connection I0, I 2. The pawls 3 will thus be retained in contact with the terminal matrix of the line throughout its movement along the elevator, and during the raising of the e1evator after casting.

As is well known, the line resistant member 4 normally occuplies the position in which it is shown in Figure l and is automatically returned to that position by means of the upper transfer slide by which the matrix line is delivered from the elevator to the distributor. This arrangement, being well known, is not illustrated, but it should be explained that the mechanism in question is utilized for also returning the pawls 3 to the line receiving position.

To ensure the necessary relative movement between the line resistant member 4 and rails 5 during such restoration of the parts to normal position, studs l8 are provided near the leftward extremity of the rails 5, which studs project outwardly from the said rails towards the elevator walls, and stop pins i 9 are secured to the said walls to co-operate with the studs l8 to limit the rightward movement of the rails 5. It is also desirable to provide means for limiting the leftward movement of the line resistant member 4, and in the constructional example shown such means consist of stop pins 20 fixed in the elevator head.

The mechanism above-described and illustrated in the accompanying drawings ensures adequate support for the terminal matrix of a line in the elevator throughout the operation of the later from the moment when the line is delivered to the elevator until it is transferred therefrom for distribution. It is to be understood, however, that the mechanism in question is described and illustrated merely as a. convenient example, and that modifications in the form of the devices may be made without departing from the invention.
